Abstract: An image sensor includes a substrate, thin lenses disposed on a first surface of the substrate and configured to concentrate lights incident on the first surface, and light-sensing cells disposed on a second surface of the substrate, the second surface facing the first surface, and the light-sensing cells being configured to sense lights passing through the thin lenses, and generate electrical signals based on the sensed lights. A first thin lens and second thin lens of the thin lenses are configured to concentrate a first light and a second light, respectively, of the incident lights onto the light-sensing cells, the first light having a different wavelength than the second light.

Abstract: A neural probe for light stimulation of a tissue is provided. The probe includes a base that has light supplying circuitry, and one or more elongated microsized shanks extending from the base. Each shank has a longitudinal axis and includes one or more waveguides extending along the shank's length, with the waveguides being optically connected to the light supplying circuitry. In addition, each of the waveguides is optically connected to a diffraction grating coupler that emits a light beam from the shank when light passes from the base through the waveguide and to the diffraction grating coupler. The emitted light beam has a propagation direction at a set angle relative to an axis that is substantially normal to the longitudinal axis of the shank. A method for stimulating a tissue using the neural probe is also provided.

Abstract: Structures for scattering light at multiple wavelengths are disclosed. Scattering elements are fabricated with different geometric dimensions and arrangements, to scatter or focus light at the the same focal distance for each wavelength, or at different focal distances according to the desired application. The scattering elements fabricated on a substrate can be peeled off with a polymer matrix and attached to a lens to modify the optical properties of the lens.

Abstract: An optical device has a first metasurface disposed over a substrate. A high-contrast pattern of the first metasurface is operable for modifying, over a first phase profile, a phase front of an incident light beam. A second metasurface, is disposed over a plane parallel to the first metasurface with a second high-contrast pattern and operable for shaping, over a second phase profile, the modified phase front of the incident light beam into a converging spherical phase front. A spacer layer, in which the modified phase front of the incident light beam diffracts, is disposed in a controllably changeable separation between the first and second metasurfaces. Controllably changing the separation between the first and the second metasurfaces by a first distance correspondingly changes the position of the focus point of the converging spherical phase front by a second distance significantly greater than the first distance.
